Just like the topic says, Nichelle Nichols is holding her final convention next May...
"on May 1 - 3, we invite you to join us for Nichelle’s final voyage with those friends and fans that love and adore her. Come spend time with this extraordinary woman—the last opportunity that you will have to celebrate with her—and join in the celebration of her incredible life and amazing achievements."
Looks like they will have plenty other guest as well.
I've had the pleasure to meet her and hear her speak at a number of other conventions, truly a wonderful person, so If its on your bucket list... this may be the last opportunity!
